| Abstract: | The communication between DCS, PLC and PC is very important in a DCS project. Foxboro's I/A series system is one of the mainDCS systems used in China. This paper majors in the three main communication methods between Foxboro'sI/A's system and other DCSs,PLCsor PCs, they are: to use the hardware to perform communication, to use the professional software to fulfill communication and user-developedprogram to achieve communication. This paper emphatically briefs some methods of communication software developed by the user and itsmain programmable functions. Through the strong and weak points comparisons between several lealized methods, the reference is providedfor users to select the appropriate communication method. |
